Ruby has a new moving GC. I just merged moving Immix in the MMTk Ruby binding. This is exciting as its the first GC that dynamically detects fragmentation in the heap and performs defragmentation. Performance isn't too great yet but I'm working on it! github.com/ruby/ruby/pu...

#rubyrelease30th I’d like to introduce Aliki, RDoc and docs.ruby-lang.org’s new theme 😄 railsatscale.com/2025-12-22-i...

Finally, www.ruby-lang.org/en/ has a new design.

Ever forget whether it's "change_table" or "alter_table", "remove_column" or "drop_column", "set_column_null" or "change_column_null"? You don't? Well, I do 😄 So, I thought it would be cool if Ruby LSP could autocomplete schema statements in migrations ✨ github.com/Shopify/ruby...

Workspace symbol search on Ruby LSP should be working much smoother now on 0.26.3, @vinistock.bsky.social and I made a bunch of fixes recently 🤘 github.com/Shopify/ruby... github.com/Shopify/ruby... github.com/Shopify/ruby...

Herb v0.8 is here! 🚀 The biggest release yet, packed with new language bindings, Linter Autofix support, Linter Fix-on-Save, a new `.herb.yml` config file, formatter improvements, Tailwind Class Sorting integration, and a ton of performance, tooling and LSP improvements! 🌿

🎉 Incredibly honored to be a Ruby Prize 2025 finalist! Thank you to everyone who has supported my work on IRB, RDoc, debug, ZJIT, and other Ruby projects. See you in Matsue! rubyprize.jp

We just publicly posted about the Rubygems.org AWS root-access security incident from September 2025, what occurred, what we verified, and the actions we’ve taken to strengthen our security processes.

I tried to explain why I don't believe the recent accusations toward my former teammates, as well as how the Ruby and Rails Infra team at Shopify operates and why it can be trusted. byroot.github.io/opensource/r...

Herb v0.5.0 is here! 🌿 Lots of fixes & improvements, plus a new `--github` flag so the Linter can annotate the offenses right on GitHub in the pull request! Plenty more is cooking, which wasn't quite ready for prime time yet 👀

Beyond performance work, I deprecated a bunch of APis in the JSON gem, and added others, so I figured it would be a good occasion to talk about API design: byroot.github.io/ruby/json/20...

ruby-lsp now has CLAUDE.md: github.com/Shopify/ruby... (generated by Claude and vetted by our team) Not sure how much it'll help the team and external contributors but I'm excited to find out 😁

So it turns out all that is needed to support RBS and ruby-lsp on JRuby is for someone to write an FFI binding to the new "pure C" RBS parser! I challenge y'all to make that happen this week. So exciting to get these key Ruby tools working on JRuby! github.com/Shopify/ruby...

I wrote a post to braindump what I'm currently working on: allowing lock-free access to class instance variables from Ractors. byroot.github.io/ruby/perform...

Today, we're announcing plans to make VS Code an open source AI editor. We believe AI development should stay true to VS Code's core principles: open, collaborative, and community-driven. Let's build the future of software development together. aka.ms/open-source-...

BTW, I’ve opened a draft PR for this: github.com/Shopify/ruby... We’re now waiting on a new VS Code API to let extensions configure the MCP connection, which will make the setup simpler & more robust.

My teammate Alexandre Terrasa wrote a great post about using inline RBS with Sorbet. We’ve been slowly adopting it at Shopify. And while we’re still improving Sorbet and all the supporting projects, it’s already working well! railsatscale.com/2025-04-23-r...

@ufuk.dev introducing Ruby Committers on stage at RubyKaigi day 3.

EN: Kicking off the first afternoon of talks at #TropicalOnRails, @vinistock is on stage discussing Strategic Standardization: Driving Innovation. 🚀🌴 PT-BR: Abrindo as palestras da primeira tarde de #TropicalOnRails, @vinistock falando sobre Padronização estratégica: direcionando inovação. 🚀🌴

Super excited to get this out of the door! There's still a lot of work to do to match the amount of data we had on RubyConferences.org, but to me it's very clear that this is the way forward for RubyEvents!

1 dia para a @tropicalonrails.bsky.social! Na minha palestra, vou falar de padronização, como ela pode ser usada de maneira estratégica, e como o Rails usa convenções. Na parte de DX, vamos falar de uma nova tentativa de padronização e vou anunciar um protótipo da Ruby LSP. Vejo vocês lá!

PoC: A Ruby MCP server (powered by Ruby LSP) interacting with the Cursor agent. Ruby MCP can provide your project's: - Dependencies - Indexed classes/modules/methods - Runtime info (powered by a Rails add-on) - Anything else supported by other add-ons to the client. Thoughts?

It's an idea my colleague Alexandre Terrasa and the team explored way back in 2020. But due to various challenges we couldn't make it work at the time. Maybe 2025 will be the year to finally make it happen? - 2020 PR: github.com/sorbet/sorbe... - 2025 PR: github.com/sorbet/sorbe...

I wrote down my personal thoughts on whether it's worth removing Ruby's GVL and what it would take. I wanted to talk about Ractors too, but this is already too long, so that's for another time. byroot.github.io/ruby/perform...

I’m available for hire. I’m an experienced Ruby, TypeScript and CSS engineer looking for a new full-time position. I can help you with performance, concurrency, testing, architecture and API design problems on tooling or product teams. I’d really appreciate any personal introductions. DMs open. 🙏

IRB 1.5.0 introduced: - The new `copy` command to easily copy an expression’s inspection result to the clipboard - Quick preview when rendering a long output - A new `ri` alias for the `show_doc` command Enjoy 😉 github.com/ruby/irb/rel...

I want to write a post about Pitchfork, but before I can get to that I need to share some thoughts. I suspect this one may be more controversial than the optimizing JSON series 😅. byroot.github.io/ruby/perform...

After 15 years off the market, I’m available for hire! I’m an effective, versatile and compassionate technical leader, and an accomplished Rubyist. I’m looking for remote Principal or Staff Engineer roles, at 4 days/week. Find out more: timriley.info/posts/hire-me

`mise` offers default gems feature. With this feature, it's easy to install ruby-lsp, ruby-lsp-rails and pry gems automatically for all rubies in system.

On this third day of Railsmas: an overlooked treasure for those who think their IDE already has everything. Open your mind, read, and see if you might just think twice about Ruby-LSP as a sign of productivity miracles yet to come. evilmartians.com/chronicles/r...

2024 is the year with the most Ruby talks in a single year, ever! This is the first time we beat the previous all-time record from 2015! Ruby is so back!

What @hsbt.org shared is very important for the whole community. We all need to do our part to ensure that Ruby 3.4 is rock solid. If you maintain an app or a gem, run its CI against Ruby head. Find regressions & report them. Find incompatibilities & fix them in your code. This work helps us all.

🎙️New Episode of Code and the Coding Coders who Code it! Episode 43 with @st0012.dev podcast.drbragg.dev/episodes/epi... #ruby #Rails #code #coding #coders #podcast

Had a great chat about my recent work around Sorbet and Ruby documentation 😄

Rubyists, have you ever wanted more features from SQLite? I'm excited to announce the `sqlean` ruby gem! github.com/flavorjones/... packaging precompiled extensions from antonz.org/sqlean/ for things like unicode, hashing, regexps, time, fuzzy strings, math, and even CSV support! #ruby #sqlite

A good language’s default tooling should cover most of its developers’ needs right out of the box 🙂

Hello, hello Bluesky!!! This is going to be our official WNB.rb account!! Who do we need to follow in the #Ruby community??

I’m extremely honoured to have been nominated for the Ruby Prize this year for my work in the Ruby LSP, DX in general and talks given at conferences. Congratulations to the finalists! rubyprize.jp

Rubyists! sqlite3 gem v2.3.0 is released, introducing `Database#optimize`, some new compile-time features enabled, and an eight-year-old encoding bug fixed! github.com/sparklemotio... #ruby #sqlite

In case you missed it, I recently wrote an article about Ruby’s documentation: st0012.dev/a-rdoc-maint...

It seemed kind of redundant at the time, but I ended up building a Ruby LSP plugin for Neovim, just to smooth over some setup quirks. It's had a nice side-effect of where I could maybe add some nicer things that don't come out of box with nvim-lspconfig. Autodetection of tooling, etc.

Worked with @jhawthorn.com to make a change to Vernier today! This PR gives us visibility in to Fibers running in Ruby. It's especially handy for identifying Fibers that are stalling your event loop (if you're using that): github.com/jhawthorn/ve...
